This Unicable II LNB is based on digital channel stacking technology and allows to connect up to 32 satellite receivers over a single coax cable. The LNB support the standard EN50494/EN50607 protocols, allowing the connected receivers to access any transponder of the received satellite (also known as ‘Dynamic’ mode).
 
Alternatively, the LNB can be configured to down-convert a programable set of up to 32 transponders (depending on the bandwidth of the desired transponders) and stack them over its output (also known as ‘Static’ mode). This mode allows an unlimited number of receivers to be connected and access these transponders.
 
Digital channel stacking technology uses fast wideband analog to digital converters and applies digital signal processing to select desired transponder channels, up convert them and stack them as IF signals over the output port. Unicable II LNBs offer a cost effective and elegant solution for distributing the satellite signals to multiple set-top-boxes (multiroom) or multi-tuner PVRs over existing cabling hence significantly reducing cost and complexity of the installation at the subscribers’ homes. The Static mode, allowing an unlimited number of receivers to be connected to the LNB over a single cable distribution, makes installations in buildings, campuses and closed communities substantially cheaper and simpler than ever before. The operating mode (dynamic/static), output power level, channel bandwidth, UB frequencies and dish alignment mode are all programmable and can be configured and updated in the field using Inverto’s SatPal Controller*.
 
The LNB can be powered over a connected STB or by an AC/DC adapter over a power inserter in case the STB is unable to provide the necessary power. Unicable II is backward compatible, fully compliant with both EN50494 and EN50607 standards and integrates seamlessly into EN50494-only or mixed EN50494/EN50607 installations of compatible STBs, Next Generation PVRs and HGWs.

FAQ
Q: What is an LNB?
A:
An LNB - Low Noise Block (also called an LNC- Low Noise Converter), it is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish and its purpose is to collect and amplify the satellite signal received from the dish and then down convert the signal to lower more manageable IF frequency which can then be carried over standard coaxial cabling to the receiver.
Q: What is a feedhorn?
A:

The feedhorn is a part of the LNB and works like a directional horn. Its function is to capture the signals reflected from the dish and to shield the LNB from receiving extraneous radiation from other sources. These collected signals are then passed form the horn to the electronics within the LNB.

Q: What is the difference between a Quad and Quattro LNB?
A:
A quad or quad switch LNB is an LNB where the multi switch is integrated into the LNB and gives 4 independent output ports for the connection of 4 receivers. A Quattro LNB has 4 outputs and each of the output’s is set to one of the differing polarities, the 4 outputs are V/L, V/H, H/L & H/H. A Quattro LNB is normally used to feed a multiswitch which then allows the distribution of the signal to any number of satellite receivers. All four outputs of a Quattro LNB are marked accordingly with V/L, V/H, H/L & H/H to avoid confusion and malfunctions when connecting to the multiswitch.
Q: What is the HsQuare Technology?
A:

HsQuare is a unique waveguide technology which may be coupled with a slightly larger feed horn design to deliver better RF performances compared with common circular microwave waveguides.

Q: What is a monoblock LNB?
A:
This design consists of two independent LNBs in a single housing and allows a user the potential of receiving the signal from two different satellites which are at slightly different orbital opposition from a single dish installation. The switching between the satellitesis achieved via the use of DiSEqC signals or Toneburst (Mini DiSEqC). Monoblock LNB’s are available mostly for satellites with a fixed 4.3° or 6° spacing and the range covers Ku band monoblock switch single, twin and quad outputs.
 
Example where a 6° monoblock LNB could be used is for the reception of ASTRA 1 (19.2° East) and Hotbird (13° East) or with 4.3° distance for the reception of ASTRA 1 (19.2° East) and ASTRA 3 (23.5° East).
Q: Why can I receive only one satellite with my monoblock LNB?
A:
For dual satellite reception the dish is normally initially aligned to the weaker of the two satellites and then some slight adjustment can be made ensure the best possible reception from both the satellites. A monoblock installation will require a slightly larger dish size than if only one satellite location had been chosen. Monoblock LNBs are designed to work on a specific dish size and it’s important that the correct dish size is installed or both satellites signals may not be picked up at a sufficient level of strength to guarantee reliable reception.
Q: What is a wideband LNB?
A:
With a wideband LNB having only one local oscillator (e.g. 10.4GHz), and captures the full frequency spectrum of the satellite (300MHz to 2350MHz) which are delivered over two outputs from the LNB. One output carries all the vertically polarized signals whilst the second output carries all the horizontally polarized outputs. Whilst most of the current multiswitches on the market do not accept a wideband input the newer multiswitches such as newer Unicable switches are capable of accepting this as their input.
 
Caution: Wideband LNBs are not conventional twin LNBs. Wideband LNBs can be connected to a Unicable multiswitches that is designed for this purpose, or, if connected directly to a receiver, only with a suitable tuner.
Q: What does Unicable mean?
A:
Unicable is a new method for distributing satellite television. Several receivers (currently up to 32 in accordance with standard EN 50607) can be connected to only one single chain which is not possible with a conventional satellite distribution (star distribution in multi-switch mode).
